Sensitivity of detecting interictal epileptiform activity using rapid reduced montage EEG.

Objective: Rapid EEG devices (REDs) have demonstrated substantial benefit regarding reduced time to performance of study and diagnosis in cases where urgent EEG is needed to evaluate patients for potentially revealing nonconvulsive status epilepticus and seizures. However, urgent EEG is also important in identifying cases regarding the need for initiation of antiseizure medication as well as triaging the use of continuous EEG monitoring. Some forms of REDs have a reduced montage (RRME) with electrode derivations that are one-half of standard recordings.

A review of acute symptomatic seizures during awake craniotomy for tumour resection.

Purpose: Awake craniotomy (AC) is a procedure often performed concomitantly with direct electrical cortical stimulation (DES) and electrocorticography (ECoG) during functional brain mapping. Patients undergoing AC are at risk of acute symptomatic seizures, including intraoperative (IS) and early postoperative seizures (EPS) which can lead to higher risk of morbidity. Predicting those who are at risk of IS and EPS could alert clinicians and provide the ability to closely monitor and consider management changes in the acute setting to prevent seizures.

Minimally Invasive Epilepsy Surgery.

Surgery remains a critical and often necessary intervention for a subset of patients with epilepsy. The overarching objective of surgical treatment has consistently been to enhance the quality of life for these individuals, either by achieving seizure freedom or by eliminating debilitating seizure types. This review specifically examines minimally invasive surgical approaches for epilepsy.

Pupillary constriction on stimulation of the parietal cortex-A novel finding.

Pupillary changes can be an important semiologic feature in focal epilepsy. Though the subcortical networks involving pupillomotor function have been described, cortical generators of pupillary dilation and constriction in humans are not well known. In this report, we describe a case of pupillary constriction occurring during seizures in a patient with drug resistant focal epilepsy.
